Stuck in Samsung startup loop

I have rooted my phone, via these instructions here. Then I was trying to update to DL30 via these instructions here. Both steps seemed to work with no problems. I finshed installing the new_cwm.zip file, rebooted, but now my phone is stuck in the Samsung start up screen.

I'm not on my computer to look up links, but what you should do is to find Adrynalyn's instructions to flash the DL09 update on your phone.
This will get you back on 2.1 and rooted, with clockwork installed, then you can retry the 2.2 update. When you do this you can also use the new clockwork posted today by JT instead of the one in the post you linked. This one will work better.
Sorry I can't link the threads but you should be able to find them.

I should have added in my original post that i am a complete novice. My original goal when i started was to upgrade to froyo. I was able to ODIN back to the stock DI01where I can at least use the phone and text - much better from when I posted the original thread.

I found both Adrynalyn and JT's post, but each post have several download options, and I'm not quite sure which file is the best file i need. If you could give me guidance to the the most updated files needed to be downloaded and the order to run the process, that would be very helpful.
